📞 Phone Parser #

A Dart library for parsing, validating, and formatting phone numbers — always in sync with Google’s libphonenumber.

Unlike traditional phone number libraries where you wait for maintainers to publish updates, phone_parser auto-syncs with Google’s libphonenumber. That means whenever Google ships a new release, your project gets the latest intelligence instantly — no delays, no stale metadata, no headaches.

✨ Whether you’re building a shiny new Flutter app or running a Dart backend server, phone_parser is smart, reliable, and always up-to-date.

So you can focus on building while phone_parser takes care of keeping things current. 💡

🚀 Why phone_parser? #

Google’s libphonenumber is fantastic, but:

• ❌ It isn’t natively available for all platforms.
• ❌ You often need channels or bindings to use it.
• ❌ Updates depend on maintainers.

✅ phone_parser solves this:

• Works across all Dart platforms (Flutter, backend, CLI).
• Ships with auto-synced metadata from Google’s libphonenumber.
• A fork of phone_numbers_parser with seamless updates built-in.

✨ Features #

• ✅ Validation — Check if a number is valid, by type (mobile, fixed line, VoIP, etc.)
• ✅ Formatting — Format numbers region-specifically
• ✅ Phone Ranges — Expand or compare ranges of numbers
• ✅ Number Extraction — Find phone numbers in plain text
• ✅ Eastern Arabic digits support
• ✅ Best-in-class metadata — Always fresh from Google’s libphonenumber

📦 Installation #

dependencies:
  phone_parser: ^latest

🛠 Usage #

Start with the PhoneNumber class:

import 'package:phone_parser/phone_parser.dart';

void main() async {
  // Load metadata before parsing numbers
  await MetadataFinder.readMetadataJson("./");

  final frPhone0 = PhoneNumber.parse('+33 655 5705 76');

  // Parsing in different contexts
  final frPhone1 = PhoneNumber.parse('0 655 5705 76', callerCountry: "FR");
  final frPhone2 = PhoneNumber.parse('011 33 655-5705-76', callerCountry: "US");
  final frPhone3 = PhoneNumber.parse('011 33 655 5705 76', destinationCountry: "FR");

  final isAllEqual = frPhone0 == frPhone1 && frPhone0 == frPhone2 && frPhone0 == frPhone3;
  print(frPhone1);
  print('All representations equal: $isAllEqual');

  // ✅ Validation
  print('valid: ${frPhone1.isValid()}'); 
  print('valid mobile: ${frPhone1.isValid(type: PhoneNumberType.mobile)}');
  print('valid fixed line: ${frPhone1.isValid(type: PhoneNumberType.fixedLine)}');

  // ✅ Extract numbers from text
  final text = 'hey my number is: +33 939 876 218, or call me on +33 939 876 999';
  final found = PhoneNumber.findPotentialPhoneNumbers(text);
  print('Found: $found');
}

✅ Validation #

final valid = phone.validate();
final validMobile = phone.validate(type: PhoneNumberType.mobile);
final validFixed = phone.validate(type: PhoneNumberType.fixedLine);

🎨 Formatting #

Region-specific formatting that respects local conventions:

final phoneNumber = PhoneNumber.parse('2025550119', destinationCountry: IsoCode.US);
print(phoneNumber.formatNsn()); // (202) 555-0119

🔢 Ranges #

Work with phone numbers like numbers:

final first = PhoneNumber.parse('+33 655 5705 00');
final last = PhoneNumber.parse('+33 655 5705 03');

final range = PhoneNumber.getRange(first, last);
print('Count: ${range.count}');
print('Expanded: ${range.expandRange()}');

final one = PhoneNumber.parse('+33 655 5705 01');
final two = PhoneNumber.parse('+33 655 5705 02');

if (one.isAdjacentTo(two)) print('We are adjacent');
if (one.isSequentialTo(two)) print('$two comes after $one');

final three = two + 1;
print('Still a phone number: $three'); // +33 655 5705 03
